When a car is described as moving in a straight line at a constant speed of 20 meters per second, it means that the vehicle travels in a linear path without changing direction. This speed of 20 meters per second indicates that for every second that passes, the car covers a distance of 20 meters.
To visualize this, let’s consider a scenario where the car starts from a position that is 200 meters away from a specific point, such as a traffic light or a stop sign. If the car maintains this constant speed, it will take a certain amount of time to reach that point.
To calculate how long it takes for the car to travel the initial 200 meters, we can use the simple formula:
Time = Distance / Speed
In this case, the distance is 200 meters and the speed is 20 meters per second. Plugging in these values:
Time = 200 meters / 20 meters per second = 10 seconds
This means that from its starting point, the car will take 10 seconds to reach the designated point. During this entire period, the car’s speed stays constant, which contributes to a smooth driving experience.
In summary, a car moving at a constant speed of 20 meters per second, starting 200 meters away from a point, will cover that distance in 10 seconds while maintaining its linear trajectory.
